在link_to rails中传递参数的问题

Question

I'm having trouble passing a param through a link_to in Rails using the below code:

<%= link_to new_registration_path, {:workshop => @workshop.id } do %>

When I pry into the controller, the :workshop is not being included in the params (only controller and action).

Is this a strong params issue?

Answer 1

The workshop param has to be passed to the new_registration_path helper instead of passing it to link_to , like this:

<%= link_to new_registration_path(workshop: @workshop.id) do %>

If you want the URL to be like /something/123 instead of /something?workshop=123 , you can change how your route is defined on routes.rb :

get something/:workshop

and then you can pass workshop: 123 to the URL helper.
